RTX interview questions

I was previously an intern for Raytheon and was asked to come on full time. I had my pick at which office I wanted to work at so I decided to try out the Maryland area. I was given a phone interview early in the week, that went well and then I was scheduled to fly out to Maryland that next week. Once I arrived, they took me to a room with 3 other employees and they took turns telling me about themselves and then grilled me with technical questions. At the end, I was given vulnerable C code and asked to step through it and explain the vulnerabilities and how I would fix them. Then there was a simple coding exercise in C. Finally, I was given a tour of the office. The entire process that day took around 2 hours, give or take
